DAVID JACKSON AND JOHN OSTERLOI-I, OF NEW YORK, N. Y.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 529,794, dated November27, 1894.

Application filed October 11, 1893.

To all whom it may concern:

Be it known that we, DAVID JACKSON and JOHN OSTERLOH, of the city,county, and State of New York, have invented a new and Improved Lantern,of which the following is a The invention relates to lanterns such asare used on cycles and other vehicles, and its object is to provide anew and improved cycle lantern, which is simple and durable in con-'struction, arranged to insure proper combustion and a steady, goodlight, and adaptedfor burning ordinary mineral oil as well as the moreexpensive oils and illuminants now generally used in lanterns of thisclass.

The invention consists of a lantern body carrying a detachable fount atits lower end, the said fount being provided with a burner, and formingwith the bottom of the lantern body an air chamber'connected with anupwardly-extending channel, leading to the upper end of adownwardly-extending second channel, into the lower end of which openair inlet apertures are arranged in the sides and rear of the lanternbody. V

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter described, and thenpointed out in the claims- 7 Reference is to be had to the accompanyingdrawings, forming a part of this specification, in which similar lettersof reference indicate corresponding parts in all the figures.

Figure 1 is a sectionalside elevation of they improvement on the line1-1 of Fig. 3. Fig. 2 is a cross section of the same on the line 2-2 ofFig. 1. Fig. 3 is a sectional plan view of the same on the line 33 ofFig.1; and- Fig. 4 is an inverted plan view of the cap for the lantern.I I

The improved lantern is provided with a lantern body A, preferably inthe form of a four sided truncated pyramid, as plainly shown in thedrawings, the saidbody being provided in its front A, with an openingadapted to be closed by the bulls-eye 0 held in the front door B hingedto the body of the front A, as plainly shown in Fig. 3. From the door Bextends a reflector hood D over the bulls-eye C, so as to throw thelight in the proper direction. In the sides of the body A are arrangedred or other colored lenses E Serial No. 487,847. (No model.)

serving for danger signals. In the bottom A of the body A is formed anopening A through which extends the burner F, of any approvedconstruction and held on a fount G fitted with its upper edge into thelower end of the body A, the fount being securely held in place bysprings H arranged in the sides of the fount and engaging the sides ofthe body A. See Fig. 2. By pressing the springs the fount can be readilydetached from the body for filling the fount or for other purposes.

The burner F is provided with the usual Wick rod F, extending throughone side of the'body A to be under the control of the operator on theoutside of the lantern, to regulate the flame by raising orlowering thewick. The fount G forms the basefor the truncated pyramidal lantern bodyA, and is of sufficient size to contain a large quantity of oil or otherilluminant, filled into the fount by unscrewing the burner F at the timethe fount is detached from the body, or by means of a filler providedwith a suitable screw cap. The bottom A of the body A is a suitabledistance above the top of the fount G so as to form an air chamber Jbetween the said bottom A and the top of the fount, and into this airchamber leads the lowerend of a channel J arranged in the rear of thepartition A attached tothe sides A and A of the body A.

.The channel J extends between the partition A and a secondvertically-disposed partition A likewise attached to the sides A and Abut terminating a suitable distance below the upper end of the body A,as plainly shown in Fig. 1 Between this partition A? and the back A ofthe lantern body is formed a second channel J which .connects at itsupper end with the said channel J owing tothe partition A being less'inheight than the lantern bodyA. Into the lower end of the channel J openthe air inlet apertures J formed in the backA and the sides A and A ofthe lantern body. A bottom A closes the lower end of the channel J thesaid bottom extending between the partition A the back A and the of thefount G, as will be readily understood by reference to Fig. 1.

saave i The top of the lantern body is closed'by a cap I, hinged to oneof the sides of the body A and adapted to be fastened in place at itsfree end by a suitable catch, as plainly shown in Fig. 2. The cap I isprovided in its bottom with an opening I and with a partial bottom I,which latter closes the upper end of the space formed by the upper endsof the channels J and J while the opening in the said cap I is withinthe front of the body A to carry off the products of combustion, thesame passing through the open top of the cap I, under a hood I supportedon brackets I from the top of the said cap, as plainly shown in Figs. 1and 2. The cap I when opened, gives convenient access to the interiorofthe body to clean the same and to remove and insert the reflector.

Now, it will be seen that when the several parts are in the positionshown in Fig. l, and the wick on the burner F is lighted, then theoutside air can pass through the aperture J 3 into the lower end of thechannel J and up the same between the partition A and the back A of thebody, the air finally passing from the upper end of the channel J intothe upper end of the channel J, and then down the latter to finally passat the lower end of the channel into the air chamber J and then throughthe opening A to the burner F to supply the latter with the necessaryair for combustion. The products of combustion arising from thefiamepass up in the body A into the cap I, and through the open top ofthe same under the hood I to the outside. As the partial bottom I of thecap I separates the upper ends of the channels J, J from the interior ofthe cap, no products of combustion are mixed with the incoming airpassing through the channels, so that pure air is admitted to the airchamber and consequently proper combustion takes place.

It will be seen that the circulation of air through the channels J and Jserves to keep the lantern body cool, thus avoiding radiation of a largeamount of heat from the lantern body, as is so frequently the case inlanterns as now constructed. A reflector K is removably secured to theinside of the partition A opposite the bulls-eye C, but the reflectormay be omitted as the curved partition will then serve as a reflector.

On the back A of the lantern body is arranged a fastening device L forattaching the lantern to the cycle, this fastening, device beingprovided with a toggle frame having its back L mounted to swing on apivot N attached to a projection O fastened on the outside of the back Aof the lantern body. Toggle levers L connect the back L of the framewith the front L supporting a clamping device P for attachment to thelantern supporting bar of the cycle. A spring L connects the front Lwith one of the toggle levers L so as to insure a yielding action of thefastening device to prevent undue jar to the lantern at the time thecycle passes over rough roads and any obstructions in the roadbed.

It will be seen that the air passing through the inlet apertures J andchannels J J, to the air chamber J, is not heated to any great extentand consequently contains a large amount of oxygen to insure propercombustion. The cap I is provided with a comparatively large opening Iin its bottom to permit a ready escape of the products of combustion soas to avoid undue heating of the lantern body.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1.
